Someone, tried making rubber 12th scale tires back in 89 or 90. I know I have them somewhere. They did not have rubber like we have now, so they did not hook up at all. Ended up being more of a shelf piece. lol I started running wgtr a year ago Jan. Still running the same set. TQ'ed today but ended up second thanks to my mechanic. I think I missed 2 weekends, so I have no problem with the cost.
I do wish they were a lower profile though &
I would like to try a set made for 12th's with this compound.
